Auxiliary Equipment

Auxiliary Equipment for Plastic Extrusion Lines

Auxiliary systems for plastic extrusion stabilize throughput, improve dimensional control, and extend uptime on PVC, WPC/WPE, PE, PPR, PS, sheet/board, and recycling lines. Turnkey downstream packages cover every step from feeding to packaging, with CE-conforming components and intelligent control.

Category Highlights

Built in Kunshan and shipped via Shanghai/Ningbo, with typical lead times within 60 days. Patented designs, Siemens/ABB electrics, and ISO 9001:2015 processes support reliable operation. Capacity exceeds 120 complete lines per year. We tailor solutions to your formulation and validate performance before shipment.

Complete Range of Downstream Equipment

A modular range spans material handling, melt filtration and pressure control, cooling/calibration, cutting/finishing, stacking/winding, and recycling support. Select modules to match panels, profiles, pipes, sheets/boards, or pellets.

Material Handling & Feeding

Gravimetric Dosing & Blending

Recipe control and anti-bridging design deliver ±0.3–0.5% accuracy and faster changeovers.

Hopper Dryers & Dehumidifiers

Closed-loop dehumidification and insulated hoppers limit moisture defects in hygroscopic and WPC compounds.

Vacuum Loaders & Central Conveying

Wear-resistant loaders and sealed networks automate multi-extruder supply with minimal contamination.

Melt Filtration & Pressure Control

Screen Changers (Manual/Automatic)

Options for high-fill and recycled streams maintain stable pressure with minimal interruptions.

Melt Pumps

Precision pumps smooth flow for better gauge control on sheets, boards, and thin-wall profiles.

Cooling & Calibration

Vacuum Calibration Tables

Multi-zone vacuum and rigid stainless frames achieve tight tolerances on profiles and thin-walled pipes.

Spray/Cooling Tanks

SUS304 spray or immersion tanks with optimized circuits enable uniform, water-saving cooling.

Haul-offs (Belt/Caterpillar)

High-traction designs and synchronized drives reduce slippage and ovality across products.

Cutting, Embossing & Surface Treatment

Planetary Cutters & Saws

Synchronized motion produces burr-free pipe ends and accurate cuts on profiles and sheets.

Embossing & Brushing

Temperature-stable rolls and brushing deliver consistent textures with quick-change patterns.

Corona Treaters & Edge Trimmers

In-line corona improves adhesion; adjustable trimmers hold width tolerance and cut scrap.

Stacking, Winding & Conveyors

Stackers & Tilting Tables

Non-marking belts and programmable patterns protect glossy sheets and foamed boards.

Coil Winders

Tension control forms tight, defect-free coils with auto cut/splice options.

Discharge Conveyors & Buffers

Modular conveyors decouple steps to stabilize QA and changeovers.

Recycling & Granulation Support

Shredders, Washers, Dryers

Robust size reduction and friction/thermal drying remove contaminants and moisture before reprocessing.

Pelletizers & Degassing

Underwater or strand pelletizers with vacuum degassing produce consistent pellets with lower volatiles.

Technical Features & Options

Intelligent control: PLC/HMI with data logging, alarms, and recipes synchronizes with line speed and melt pressure; open protocols enable line-wide monitoring. Build and safety: Siemens/ABB electrics, quality hydraulics, stainless contact parts, and guarded mechanisms support continuous operation. Efficiency: variable-speed drives, heat recovery, and closed-loop water systems help reduce utilities. Compatibility: calibrated designs handle rigid/flexible PVC, wood-filled composites, and polyolefins with quick-change kits.

Typical Specifications & Parameters

• Calibration tables: 4–9 m, multi-zone vacuum up to −0.08 MPa, fine leveling.


• Haul-off: up to 60 kN pull, 0.2–20 m/min speed range.


• Cutting: planetary pipe cutting to 630 mm OD; sheet/profile widths to 2100 mm, ±0.5–1.0 mm accuracy.


• Dosing: ±0.3–0.5% accuracy, 50–1500 kg/h throughput.

Applications & Use Cases

• PVC wall/ceiling panels: embossing, vacuum calibration, soft-stack handling to protect gloss and gauge.


• PVC profiles (windows/doors/trims): precise cooling, haul-offs, and saws to maintain edges and dimensions.


• Pipes (PE, PVC, PPR): filtration, sizing, cooling, haul-offs, and planetary cutters for roundness and clean ends.


• WPC/WPE decking/fencing: dehumidifying dryers, robust haul-offs, and texturing for filled compounds.


• PVC sheet/board and PS foam: melt pumps, wide cooling, accurate cutting, and stackers for flatness and finish.

How to Select Auxiliary Equipment

• Throughput and speed: match cooling capacity, haul-off power, and winder tension to peak rates.


• Dimensional accuracy and surface: use multi-zone calibration, pressure control, and clean cutting for tight specs.


• Formulation and moisture: specify drying, dosing precision, and filtration for hygroscopic or filled materials.


• Footprint, utilities, budget: choose modular units that fit your layout and scale with demand.

Compliance & Quality Assurance

Produced under ISO 9001:2015 with CE conformity. OEM certificates for Siemens/ABB electrics and branded hydraulics support traceability and uptime.
